The two rotor blades of 31-in. radius rotate counterclockwise with a constant angular velocity w = 0 = 2.2 rad/sec about the shaft at O mounted in the sliding block. The acceleration of the block is 20 = 4.1 ft/sec. Determine the magnitude of the acceleration of the tip A of the blade when (a) 0 = 0, (b) 6 = 90°, and (c) 9 = 180º. Does the velocity of O or the sense of w enter into the...
Please answer the following questions: 12. The angle between two forces 1700 N and 2500 N is 37° when placed tail to tail. What is the magnitude of the resultant force? 9. The blades of a wind turbine are 116 feet long. The propeller rotates at 15 revolutions per minute. (a) Find the angular velocity of the propeller in radians/sec. (b) Find the linear velocity of the tips of the blades. Round your answers to four significant digits. 10. The...
